SPECIFICATION forming part of Letters Patent No. 499,008," daten .rune 6,1893. Application iiled- July 12, 1892. Serial No'. 4,559,834. (No modeh) To all whom/it mJay'con/)cernk zen of .the United States, 4residingat Camden., in the county of Camden and Stateof' New Jersey, have k,invented anew and useiul'lmprovement in Windows, of which4 the followingisa specification." y l vThe cloudin' and frostinor ortranslucencv D b y of the windows of a locon1otive-cab,is usually occasioned by steam, vapor` o f rain leakingin between thecab and boiler, and the leakage- -of the variousiboilercocks located within'the cab, which condenses on the' inside ot the vpanes of glass.; l

The invention consists in the peculiar construction andarrangement of parts as will be hereinafter fully pointed out and claimed.

On reference to theaccompanying sheet of .drawings making part of ythis specification:

Figure 1 is a front elevation 'of Valocomotive- 'cab front-window sash, showing the means',

preferably, employed for directing a current of air upward against the inside of a pane of glass, intervening between itand the cab atmosphere; and, Fig.2 is a transverse section.

of' Fig. l, thepane 'of glass and deflectors being shown in heavy black instead of sectional lines. i

Similar letters refer to similarparts in the several views..

I The sash, A, of the front-window of a loco motive-cab, for putting my invention into practice, has its light space composed, preferably, of three parts, viz': the bottom one or air-currentdeflector,` B; the mddle one or pane of glass, C,through which the engineer sights; and the ltop one or air-current `dehector,- D. The sight-pane, C, is in chisinstance inclined inwardly from the bottom to, the top of the sash, A, and overlaps the bottomdeiiector, B, which inclines toward it, a space or air-channel, a, intervening. The top deector, D, which overlaps the pane, C, at its top end on the outside, is inclined toward the pane,a space or air. channel, b, intervening as below. The space, ct, serves to direct a current of air from without upwardly and against the entire pane, while the space, indirects a,

current of air above said pane, which assists" i the inside current bydrawing and suction.,

v Y f The pressure and force of the outside air in Be 1t known that I, JOSEPH BRUDON, aci'tits lpassage .through the spaces orchannels, a. h, is proportioned to the velocity ot the locomotive-engine. Its direction, as shown by the arrows, is given to itby the deflectors B, D, as itis forced' up along the inside ofthe pane,

G, intervening betweenitand the atmosphere of the cab. The upper air-space or channel, h, serves to draw a current of air along the loutside of the panejand direct it above the inside current vthrough the space, b, which it raidsby suction, in its passage over the surcomotive-cab. It is applicableto any win? dow which is so located that a' current of air can be had, which will intervene between the inside of .the glass, and the atmoshere of the room or place of the window, making the temperature alike on both .sides of th-e glass.l

I donotcoufine myself to 'the sash A, deliectors B, D, and sightfpane C, for putting my invention in practice; modifications may be made, and other devices usedwhich will apply with equal effect. Theintervening aircurrent can be directed in any other possible direction over the inside of the sight-glass or pane C.

1. In a window, the combination 'with a frame 'and a sight pane carried bythe frame, of a deector arranged within theframe, beyond one end of the sight.. pane, and laterally separated from said pane to forni a passage through which'air can pass in contact with the surface of the sight pane, substan-4 tially as described. Y

. 2. In a' window, the 'combination with a frame and a sight pane secured tothe frame, of a deflector arranged Vwithin the frame belowthe sight pane' therein and having its upper end extending above and to one-side of the lower end of said pane whereby apassage is formed between the sight pane and deiector through which air can pass in contact with the surface of the sight pane, substantially as described. 3. In a window, the combination with a frame and a sight pane secured within the.

4. A window consisting,r of :L frame, :L sight pane fitted within the frame, mili' two reversoly inclined lleectors secured within the fru me above und below the sight pane, said (lelleci 'ors uxtouili ngboyoml'the upper. und lower edges of the sight pane and being' soinclined as to form spaces or passages between themselves and said paney through which air can pass in Contact with the sight penesubstanj tizilly us and for the purpose specified.

In testimony whereof I aix my signature in presence of two witnesses.
